Paul, writing to Titus, couldn’t be more clear about what believers should be about:

The saying is trustworthy, and I want you to insist on these things, so that those who have believed in God may be careful to devote themselves to good works. These things are excellent and profitable for people. But avoid foolish controversies, genealogies, dissensions, and quarrels about the law, for they are unprofitable and worthless. (Titus 3.8, 9, ESV)

The leader insists on “these things” – what things? Here are the preceding verses, Titus 3.1 – 7, bulleted out for clarity: 

• Remind them to be submissive to rulers and authorities, to be obedient, to be ready for every good work, to speak evil of no one, to avoid quarreling, to be gentle, and to show perfect courtesy toward all people. (Be well behaved)
• For we ourselves were once foolish, disobedient, led astray, slaves to various passions and pleasures, passing our days in malice and envy, hated by others and hating one another. (Not be given to passions and hatred)
• But when the goodness and loving kindness of God our Savior appeared, he saved us, not because of works done by us in righteousness, but according to his own mercy, by the washing of regeneration and renewal of the Holy Spirit, whom he poured out on us richly through Jesus Christ our Savior, so that being justified by his grace we might become heirs according to the hope of eternal life. (Understand the gospel)

Back to verses 8 and 9: remind them of these things so that:

• Believers may devote themselves to good works – profitable for people
• Believers avoid foolish controversies…dissensions, and quarrels about the law – that is, discussion of details of scripture or theological practice. Such things are “unprofitable and worthless”
• Also, “avoid quarreling.” Social media is nothing but quarreling these days. Avoid it! It’s a medium for malice, hating others, etc. Believers have no place engaging in those activities.

Wow. He leaves no doubt…

And let our people learn to devote themselves to good works, so as to help cases of urgent need, and not be unfruitful. (Titus 3.14, ESV)
